为什么这个模块没有加载？

  • 772

我已经安装了第三方包librealsense。作为下载的一部分，它设置uvcvideo为编译为内核模块。完成后，我重新启动到修改后的内核。我可以看到我的uvcvideo.ko文件，但由于某种原因它没有加载。这里发生了什么？

$ sudo modprobe uvcvideo
modprobe: ERROR: could not insert 'uvcvideo': Unknown symbol in module, or unknown parameter (see dmesg)

$ uname -r
4.4.0-47-generic
$ ls /lib/modules/4.4.0-47-generic/updates/dkms/
uvcvideo.ko  vboxguest.ko  vboxsf.ko  vboxvideo.ko

    我修改了脚本以支持新内核（4.8.0-xx）。

    链接：https ://github.com/JJHu1993/librealsense-patch.git

    ``` 补丁内核模块创建成功

    卸载模块 uvcvideo 应用补丁模块 uvcvideo 插入 uvcvideo 成功

    脚本已成功完成。请参阅安装指南以获取更多说明。

    jjhu@jjhu-computer:~/projects/librealsense$ uname -r 4.8.0-52-generic

    ```
